POTS is autoimmune?

This is actually a complicated subject! The science right now strongly suggests that POTS is autoimmune but it’s not confirmed yet. I personally bet that it is— it is mostly found in women (like autoimmune) & many people with POTS have other autoimmune diseases. I too have celiac and POTS myself & celiac seemed to trigger my POTS actually. Here’s an article that explains more of the science of it: https://www.dysautonomiainternational.org/blog/wordpress/new-evidence-of-autoimmunity-in-pots/

POTS and other forms of dysautonomia is classified and autonomic nervous system problems not auto immune

I know POTS as it relates to Ehlers Danlos Syndrome which is an inherited connective tissue disorder that can effect the heart. But si do wonder....

I have POTS also and have heard the same but so far it’s said not to be an autoimmune but that POTS can be CAUSED by an autoimmune disease.

Also it’s very likely that someone else in your family has/had celiac and just went undiagnosed. It’s much more likely that you inherited celiac and that celiac triggered your POTS than that POTS caused celiac. Celiac is highly genetic and POTS is more complicated genetically
